Subject: [PATCH] RH: fixup udev rules for redhat
The multipath rules need to run after scsi_id is run. This means moving
them after 60-persistent-storage.rules for redhat. Redhat also uses a
different naming scheme for partitions than SuSE.

Subject: [PATCH] RH: Remove the property blacklist exception builtin
Multipath set the default property blacklist exceptions to
(ID_SCSI_VPD|ID_WWN). This has the effect of blacklisting some internal
devices. These devices may never have multiple paths, but it is nice
to be able to set multipath up on them all the same. This patch simply
removes the default, and makes it so that if no property
blacklist_exception is given, then devices aren't failed for not matching
it.

Subject: [PATCH] RH: don't start without a config file
If /etc/multipath.conf doesn't exist, don't start multipathd and blacklist
all devices when running multipath. A completely blank configuration file
is almost never what users want. Also, people may have the multipath
packages installed but don't want to use them. This patch provides a
simple way to disable multipath. Simply removing or renaming
/etc/multipath.conf will keep multipath from doing anything.

Subject: [PATCH] RH: add mpathconf
mpathconf is a program (largely based on lvmcomf) to help users
configure /etc/multipath.conf and enable or disable multipathing. It
has a couple of built-in options that can be set directly from the
command line. But, mostly it is used to get a multipath.conf file
with the OS defaults, and to enable and disable multipathing via
a single command.

+.TH MPATHCONF 8 "June 2010" "" "Linux Administrator's Manual"
+.SH NAME
+mpathconf - A tool for configuring device-mapper-multipath
+.SH SYNOPSIS
+.B mpathconf
+.RB [\| commands \|]
+.RB [\| options \|]
+.SH DESCRIPTION
+.B mpathconf
+is a utility that creates or modifies
+.B /etc/multipath.conf.
+It can enable or disable multipathing and configure some common options.
+.B mpathconf
+can also load the
+.B dm_multipath
+module, start and stop the
+.B multipathd
+daemon, and configure the
+.B multipathd
+service to start automatically or not. If
+.B mpathconf
+is called with no commands, it will display the current configuration, but
+will not create of modify
+.B /etc/multipath.conf
+
+The default options for mpathconf are
+.B --with_module
+The
+.B --with_multipathd
+option is not set by default. Enabling multipathing will load the
+.B dm_multipath
+module but it will not immediately start it. This is so
+that users can manually edit their config file if necessary, before starting
+.B multipathd.
+
+If
+.B /etc/multipath.conf
+already exists, mpathconf will edit it. If it does not exist, mpathconf will
+create a default file with
+.B user_friendly_names
+set and
+.B find_multipaths
+set to \fBon\fP. To disable these, use the
+.B --user_friendly_names n
+and
+.B --find_multipaths off
+options
+.SH COMMANDS
+.TP
+.B --enable
+Removes any line that blacklists all device nodes from the
+.B /etc/multipath.conf
+blacklist section. Also, creates
+.B /etc/multipath.conf
+if it doesn't exist.
+.TP
+.B --disable
+Adds a line that blacklists all device nodes to the
+.B /etc/multipath.conf
+blacklist section. If no blacklist section exists, it will create one.
+.TP
+.B --allow \fB<device>\fP
+Modifies the \fB/etc/multipath/conf\fP blacklist to blacklist all
+wwids and the blacklist_exceptions to whitelist \fB<device>\fP. \fB<device>\fP
+can be in the form of MAJOR:MINOR, a wwid, or the name of a device-mapper
+device, either a multipath device, or any device on stacked on top of one or
+more multipath devices. This command can be used multiple times to allow
+multiple devices. \fBNOTE:\fP This action will create a configuration file that
+mpathconf will not be able to revert back to its previous state. Because
+of this, \fB--outfile\fP is required when using \fB--allow\fP.
+.TP
+.B --user_friendly_names \fP { \fBy\fP | \fBn\fP }
+If set to \fBy\fP, this adds the line
+.B user_friendly_names yes
+to the
+.B /etc/multipath.conf
+defaults section. If set to \fBn\fP, this removes the line, if present. This
+command can be used along with any other command.
+.TP
+.B --recheck_wwid \fP { \fBy\fP | \fBn\fP }
+If set to \fBy\fP, this adds the line
+.B recheck_wwid yes
+to the
+.B /etc/multipath.conf
+defaults section, or sets an existing line to \fByes\fP. If set to \fBn\fP, this
+sets an existing \fBrecheck_wwid\fP line to \fBno\fP. This command can be used
+along with any other command.
+.TP
+.B --find_multipaths\fP { \fBon\fP | \fByes\fP | \fBy\fP | \fBoff\fP | \fBno\fP | \fBn\fP | \fBstrict\fP | \fBgreedy\fP | \fBsmart\fP }
+If set to \fB<value>\fP, this adds the line
+.B find_multipaths <value>
+to the
+.B /etc/multipath.conf
+defaults section. This command can be used along with any other command.
+\fBy\fP and \fBn\fP can be used instead of \fByes\fP and \fBno\fP.
+.TP
+.B --property_blacklist \fP { \fBy\fP | \fBn\fP }
+If set to \fBy\fP, this adds the line
+.B property "(SCSI_IDENT_|ID_WWN)"
+to the
+.B /etc/multipath.conf
+blacklist_exceptions section. If set to \fBn\fP, this removes the line, if
+present. This command can be used along with any other command.
+.TP
+.B --enable_foreign\fP { \fBy\fP | \fBn\fP }
+If set to \fBy\fP, this adds the line
+.B enable_foreign ".*"
+to the
+.B /etc/multipath.conf
+defaults section. if set to \fBn\fP, this removes the line, if present. This
+command can be used along with any other command.
+.TP
+.B --option \fB<option_name>:[<value>]\fP
+Sets the defaults section option \fB<option_name>\fP to \fB<value>\fP. If the
+option was not previously set in the defaults section, it is added. If it was
+set, its value is changed to \fB<value>\fP. If \fB<value>\fP is left blank,
+then the option is removed from the defaults section, if was set there. This
+command can be used along with any other command.
+.TP
+.B --outfile \fB<filename>\fP
+Write the resulting multipath configuration to \fB<filename>\fP instead of
+\fB/etc/multipath.conf\fP.
+.SH OPTIONS
+.TP
+.B --with_module\fP { \fBy\fP | \fBn\fP }
+If set to \fBy\fP, this runs
+.B modprobe dm_multipath
+to install the multipath modules. This option only works with the
+.B --enable
+command. This option is set to \fBy\fP by default.
+.TP
+.B --with_multipathd { \fBy\fP | \fBn\fP }
+If set to \fBy\fP, this runs
+.B service multipathd start
+to start the multipathd daemon on \fB--enable\fP,
+.B service multipathd stop
+to stop the multipathd daemon on \fB--disable\fP, and
+.B service multipathd reload
+to reconfigure multipathd on \fB--user_frindly_names\fP and
+\fB--find_multipaths\fP.
+This option is set to \fBn\fP by default.

Subject: [PATCH] RH: add wwids from kernel cmdline mpath.wwids with -A
This patch adds another option to multipath, "-A", which reads
/proc/cmdline for mpath.wwid=<WWID> options, and adds any wwids it finds
to /etc/multipath/wwids. While this isn't usually important during
normal operation, since these wwids should already be added, it can be
helpful during installation, to make sure that multipath can claim
devices as its own, before LVM or something else makes use of them. The
patch also execs "/sbin/multipath -A" before running multipathd in
multipathd.service

exists, and if it does, try to read the state from there. If that fails,

Since the license issue has been resolved, and there are problems with
the command completion with libedit, use libreadline.
